Running back Tre Mason allowed two sacks after failing to pass protect in the Rams' preseason game Saturday versus the Packers, according to the St. Louis Post-Dispatch. On two consecutive plays, the rookie failed to pick up blitzes, and each resulted in a sack. Speaking after the game, head coach Jeff Fisher said Mason "needs to keep working on" his pass protection-skills. Mason is currently the Rams' third-string RB, behind Zac Stacy and Benny Cunningham.

Fantasy Analysis:

This is a bad development for Mason. Many expected to see the rookie challenge Stacy for carries in the coming year, and the Rams publicly opened up their RB1 job to competition going into camp. However, if he can't stop the blitz, Mason won't see the field on third downs much, and that may limit his utliity in the Rams' offense. For the moment, he is still behind Cunningham for the No. 2 spot. Mason may be slightly overvalued, going as a 15th-round pick on average in fantasy drafts.
